// 2007-04-10 (last updated: 2007-08-01)
// Author: Aaron McBride (http://www.apejet.org/aaron/)
// License: public domain (attribution appreciated)
// Description: Remembers (per computer) which tab you last selected
// on the Google personalized home page.  This can be useful if you want 
// to create a tab for home and one for work.  No more switching back and forth
// manually.
//
// Changes:
// 0.2 - 2007-07-30
//       I finally got around to making this work again,
//       fixed another bug, and cleaned it up a bit.
// 0.3 - 2007-08-01
//       fixed a bug where the click event wasn't being added
//       to tabs following the current tab (silly me)
